The proposed reworking of this panel and code will avert trouble in the future as Sugar is deployed on new hardware with new connection types.  This is achieved by restricting the action of the 'Discard ...' button to non-Sugar wireless connections (both '802-11-wireless' and '802-11-olpc-mesh'). The supporting code is reworked to allow other groups of connections to be discarded, if needed, by new code in separate control panel sections.

These changes advance Sugar's goal of providing a 'clear and simple' interface for learners.

NetworkManager interfaces are used for all code paths except for the test for wireless hardware.

NetworkManager interfaces are used for all code paths, and while OLPC 13.2.0 uses NetworkManager 0.9.8.1-3.git20130514.fc18, which does not list wireless devices when the radio is disabled, the dependency on NetworkManager advances to version 0.9.9, which does.

: OLPC 13.2.0 uses NetworkManager 0.9.8.1-3.git20130514.fc18, which does not list wireless connections when the radio is disabled. The kernel module database at the {{Code|/sys/module/cfg80211/holders/}} directory reveals if any wireless drivers are available in memory.

 

To minimize the chances that a manually created connection (such as 'Sugar Ad-hoc Network 2') is falsely white-listed as one of the Sugar internal ad hoc or olpc-mesh connections, each connection is tested against a discrete white list and specific to the wireless mode or connection type.

Some corner cases in behavior have been ignored: If a custom GSM (or other non-wireless or non-mesh) connection had been created, they would no longer be discarded by the 'Discard ...' button.  These could not be created by the  graphical Sugar interface, so their creators are most likely capable of discarding them if needed.
